United is the only U.S. carrier to currently have the Dreamliner in its fleet, but European regulators followed with a similar call. By this morning, carriers from other nations that fly the Dreamliner also decided to heed the warnings issued by the FAA and others.

Qatar Airways, for example, announced early this morning (Jan. 17) to stop flying its Dreamliners â?? apparently prompted into action in large part by the FAA's order.

"I previously stated that Qatar Airways will only stop operating our Dreamliners if we receive such an instruction from regulators," Qatar Airways CEO Akbar Al Baker says in a statement.

"Safety remains the number one priority for Qatar Airways," he adds. "We ensure all our aircraft meet the most stringent safety standards and this will not be compromised in any way. In light of recent events surrounding the Boeing 787 Dreamliner worldwide, we are actively working with Boeing and the regulators to restore full customer confidence in the 787."

Among the other global carriers to ground their Dreamliners are Air India, Ethiopian Airlines and Chilean carrier LAN.

Japanese carriers All Nippon and Japan Airlines â?? which account for the more than half of all Dreamliners delivered so far by Boeing â?? had already suspended their 787 operations.

And, following the order from U.S. and European regulators, Poland's LOT has done the same.

The orders were particularly poor timed for that airline, made public as LOT's maiden Dreamliner flight was en route from Warsaw to Chicago. Expected celebrations around the inaugural flight were called off and LOT flew the jet back to Poland with no passengers.
